S3 - Access-Control-Allow-Origin头

有人设法在响应头中添加Access-Control-Allow-Origin吗? 我需要的是这样的东西:

<img src="http://360assets.s3.amazonaws.com/tours/8b16734d-336c-48c7-95c4-3a93fa023a57/1_AU_COM_180212_Areitbahn_Hahnkoplift_Bergstation.tiles/l2_f_0101.jpg" />

这个get请求应该在响应中包含Access-Control-Allow-Origin: *

我的CORS设置桶看起来像这样:

<?xml version="1.0" encoding="UTF-8"?>
<CORSConfiguration xmlns="http://s3.amazonaws.com/doc/2006-03-01/">
    <CORSRule>
        <AllowedOrigin>*</AllowedOrigin>
        <AllowedMethod>GET</AllowedMethod>
        <MaxAgeSeconds>3000</MaxAgeSeconds>
        <AllowedHeader>*</AllowedHeader>
    </CORSRule>
</CORSConfiguration>

正如您所期望的那样，没有Origin响应头。

当前回答

Set CORS configuration in Permissions settings for you S3 bucket <?xml version="1.0" encoding="UTF-8"?> <CORSConfiguration xmlns="http://s3.amazonaws.com/doc/2006-03-01/"> <CORSRule> <AllowedOrigin>*</AllowedOrigin> <AllowedMethod>GET</AllowedMethod> <MaxAgeSeconds>3000</MaxAgeSeconds> <AllowedHeader>Authorization</AllowedHeader> </CORSRule> </CORSConfiguration> S3 adds CORS headers only when http request has the Origin header. CloudFront does not forward Origin header by default You need to whitelist Origin header in Behavior settings for your CloudFront Distribution.

我在加载web字体时遇到了类似的问题，当我点击“添加CORS配置”时，在桶属性中，这段代码已经存在了:

<?xml version="1.0" encoding="UTF-8"?>
<CORSConfiguration xmlns="http://s3.amazonaws.com/doc/2006-03-01/">
    <CORSRule>
        <AllowedOrigin>*</AllowedOrigin>
        <AllowedMethod>GET</AllowedMethod>
        <AllowedMethod>HEAD</AllowedMethod>
        <MaxAgeSeconds>3000</MaxAgeSeconds>
        <AllowedHeader>Authorization</AllowedHeader>
    </CORSRule>
</CORSConfiguration>

我只是点击保存，它工作得很好，我的自定义网页字体正在IE和Firefox中加载。我不是这方面的专家，我只是觉得这个也许能帮到你。

在我的例子中，我用下面的配置来解决它首先，进入权限，然后进入跨源资源共享(CORS) 然后点击编辑并粘贴下面的代码…

[
    {
        "AllowedHeaders": [
            "*"
        ],
        "AllowedMethods": [
            "PUT",
            "POST",
            "DELETE"
        ],
        "AllowedOrigins": [
            "http://www.example1.com"
        ],
        "ExposeHeaders": []
    },
    {
        "AllowedHeaders": [
            "*"
        ],
        "AllowedMethods": [
            "PUT",
            "POST",
            "DELETE"
        ],
        "AllowedOrigins": [
            "http://www.example2.com"
        ],
        "ExposeHeaders": []
    },
    {
        "AllowedHeaders": [],
        "AllowedMethods": [
            "GET"
        ],
        "AllowedOrigins": [
            "*"
        ],
        "ExposeHeaders": []
    }
]

我尝试了上面所有的答案，没有一个工作。实际上，我们需要从上述答案中总结出3个步骤来实现它:

As suggested by Flavio; add CORS configuration on your bucket: <CORSConfiguration> <CORSRule> <AllowedOrigin>*</AllowedOrigin> <AllowedMethod>GET</AllowedMethod> </CORSRule> </CORSConfiguration> On the image; mention crossorigin: <img href="abc.jpg" crossorigin="anonymous"> Are you using a CDN? If everything works fine connecting to origin server but NOT via CDN; it means you need some setting on your CDN like accept CORS headers. Exact setting depends on which CDN you are using.

更新CORS配置后，请清理浏览器缓存。我的工作后清洗缓存，而与strapi工作

首先，激活S3存储桶中的CORS。使用以下代码作为指导:

<CORSConfiguration>
 <CORSRule>
   <AllowedOrigin>http://www.example1.com</AllowedOrigin>

   <AllowedMethod>PUT</AllowedMethod>
   <AllowedMethod>POST</AllowedMethod>
   <AllowedMethod>DELETE</AllowedMethod>

   <AllowedHeader>*</AllowedHeader>
 </CORSRule>
 <CORSRule>
   <AllowedOrigin>http://www.example2.com</AllowedOrigin>

   <AllowedMethod>PUT</AllowedMethod>
   <AllowedMethod>POST</AllowedMethod>
   <AllowedMethod>DELETE</AllowedMethod>

   <AllowedHeader>*</AllowedHeader>
 </CORSRule>
 <CORSRule>
   <AllowedOrigin>*</AllowedOrigin>
   <AllowedMethod>GET</AllowedMethod>
 </CORSRule>
</CORSConfiguration>

2)如果还是不行，请确保在你的img标签中添加一个带“*”值的“crossorigin”。把这个放在你的html文件中:

  let imagenes = document.getElementsByTagName("img");
    for (let i = 0; i < imagenes.length; i++) {
      imagenes[i].setAttribute("crossorigin", "*");
